In certain kinds of .work, it is required to change frequently from a normal line-end position of the carriage to a different line-end position. The typing of telephone toll bills is. an example of such work. The toll bill lists a subscribers calls for a given period and the data for eachcall is typed on its individual line of the bill. The data for an ordinary call may consist of the place called and the toll charge. ordinary calls may be typed within uniform line lengths covering merely a place-called column and a toll-charge column of the bill. As the final character is typed for the entry in the last of these columns in a line for an ordinary call, the carriage takes a final step to what may be called .the ordinary line-end position and the carriage thereby engages and actuates a .carriage return starter or other suitable device to cause automatically the carriage to 'be returned to line-start position.

Other calls are notated with additional data such as a tax upon a toll charge exceeding a specifiedamount, and a code symbol. The bill form, therefore, includes, after the previously mentioned columns, a tax column and a code column. v

It will be understood that preparatory to extending the typing of a call line on the bill into the tax and code columns, the automatic start of the return of the carriage from the ordinary line-end position must be prevented.

An object of the invention is to provide simple, eflicient, time and labor saving means for preventing, in respect of typing extended lines, the automatic start of returning the carriage from the ordinary line-end position.

A further object is to provide means whereby, whenever there is such particular operation of the typing mechanism as occurs in or for typing a toll charge on the bill that exceeds a specified amount, that operation itself automatically determines that the carriagewill not be caused to be returned automatically from the ordinary lineend position.

Further, such particular operation may also determine that the carriage will automatically be caused to be returned from an extended-line-end position.

Still further, concomitantly with the return Thus,

movement of the carriage, it maybe determined be caused to be returned from the ordinary lineend position.

Thus, one advantage afforded by the invention is that it relieves the typist of the necessity of observing or noting whether the amount or toll charge to be typed exceeds the'specified amount and is therefore taxable. correspondingly, the typist is relieved of the necessity of making adjustment for determining automatic initiation of the return of the carriage in respect of a normal line length or an extended line length.

Figures 3 and 4 are, respectively, front elcvation and plan views of said typewriter.

Figure 5 is a perspective of the key controlled carriage controlled portions of the mechanism.

Figure 6 is.a perspective showing a portion of the mechanism at the front of the carriage. I

Figure '7 is a diagram illustrating operations of parts of the mechanism.

Figure 8 is a diagram illustrating a dificrent operation of the Figure 7 parts.

Numeral type keys l0 and alphabet type keys ll of the usual keyboard are mounted on key levers l2 connected by bell cranks 9 to type bars I3 fulcrumed at I4. By means of said keys, said type bars are-swingable upwardly and rearwardly to print against a toll bill sheet l5 feedable around a platen Hi. The platen is mounted in a carriage I! that includes a frame having a front bar l8 having roller engagement at l 9 with a front track 20, the carriage frame also having lugs 2| engaging a rear track 22. The tracks 20,

said carriage l1, and its platen IS, in letter-feed direction at operations of the type bar l3 or the usual space key 21.

The front bar l8 of the carriage has a tappet 30 to engage and depress a cam lever 3| when the carriage, in its advance, reaches a. predetermined line-end position, th depression of said cam lever in turn rocking a transverse bar 32 downwardly, said bar 32 having side arms 33 fulcrumed loosely upon a rock shaft 34 journaled in the frame side-members 23. A spring 28, Figure 4, normally upholds the bar 32 against a stop 29. Said bar 32 has an ear 35 connected by a link 3|;v to a lever 31 turnable about a pivot stud 38 on the framework. Said lever 31 engages a stud 39 on a trip link 40 for lifting the latter out of latching connection with a key-lever comb plate 4|. Said trip link 40 is pivotally connected at 43 to an arm 44 of a rock shaft 45 having suitable bearings, not shown, in the framework. Said rock shaft 45 is connected by arm 45, link 41, and arm 48 to a rock shaft 49 also suitably journaled in the framework. Said rock shaft 49 presents an arm 50 for shifting a carriage return pinion along a shaft 52, suitably journaled in the framework, to clutch or unclutch said pinion with a clutch collar 53 on said shaft 52. Said shaft 52 has a reduction gear connection 54 to a shaft 55 extendingfrom an electric motor 56 mounted upon the rear of the typewriter frame.

The rock shaft 45 has an arm- 51 to which is pivoted a pusher 58 extending rearwardly to control a switch, not shown, for starting and stopping said motor.

When the carriage tappet 30, at a line-end position of the carriage, depresses the cam lever 3|, the transverse bar 32 and link 36 are correspondingly depressed, thereby rocking the lever 31 counter-clockwise of Figure 2 to lift and release th trip link 40 from interlock with the comb plate 4|. It results that a spring 60 moves said trip link rearwardly, thereby rocking the shaft 45 counter-clockwise and the shaft 45 clockwise of Figure 2 to shift th carriage return pinion 5| into clutch with the drive shaft collar 53. The counter-clockwise rotation of the shaft 45 also acts through the pusher 58 to cause the switch, not shown, to close to start the motor 56. The resulting rotation of thepinion 59 moves the carriage rightwardly or in return direction, as viewed from the front of the machine, said pinion meshing with a rack 6| on the carriage.

When the carriage in its power driven return movement reaches a predetermined point, the carriage tappet 30 encounters and depresses a dog 62 that is keyed to the rock shaft 34 thereby I rocking said shaft 34 clockwise of Figure 2 to turn the shafts 45, as to shift the carriage return pinion 5| forwardly to unclutch it from the drive shaft collar 53. The carriage-tappetrocked shaft 34 has a suitable operating connection, not shown, to th rock shaft 45. The rotation of the shaft 45 that results in unclutching the pinion 5| from the drive shaft collar 53 also restores the trip link 40 to latched position and also draws the pusher 58 forward to cause the switch, not shown, to open to stop the motor.

A carriage-return-limiting margin-stop body Figure 4, has a stop lug 12 that cooperates with a counter-stop 13 on the front bar" H) of the carriage for finally arresting the carriage return movement after the carriage tappet 30 has served to depress the dog 52 to disconnect the carriage from the motor. Said body H is supported partly on the rock shaft 34, without binding the latter, and partly on a cross rod"|4 supported by the frame side-members 23 and held 908, to which reference may be had for other details.

A work web 19 affords a succession oftelephone-toll-bill forms "of the kind seen at Figure 1. Each form includes a Place-called column, an Amt. or toll-charge column, a Tax column and a Code column. The work web 19 may be located transversely of the carriage and platen and may b guided around the latter by means of a work web chute 80, Figure 2, of the kind described in Patent No. 1,160,459, to J.

. A. B. Smith, dated November 16, 1915.

. The first three typed lines a on the toll bill,

Figure l, exemplif ordinary calls, that is, calls for which the toll amount is less than 50. For such ordinary calls, no entry is typed in the Tax or "Code columns of the bill and hence the cam lever 3| may be placed so that as the carriage takes the letter-feed step following the typing of the last digit of the amount, the carriage tappet 30 depresses said cam lever and thereby, as hereinbefore explained, automatically initiates or causes a return of the carriage by means of the motor mechanism.

The return limiting margin stop II, 12, along with the dog 52, may be placed to terminate said return so that the carriage is left or settles at the letter space position corresponding to the place where the first character is to be'typed in the Place called" column of the bill. If desired,-

th margin stop H, 12 and dog 62 may be fixed against lateral displacement from their determined position as by a collar 02 suitably secured to the shaft 34. The dog 52 and the rock shaft 34 may have a spline connection 84 so that the dog may rock said shaft 34 and yet be shiftable along the latter.

The toll amount for a call may be or more and, in that case, a tax charge is imposed and is to be listed on the bill in the Tax column and a code symbol may also be listed in the Code column. The typing of the line on the bill for such call, therefore, extends into the tax and code columns of the bill as exemplified by the lines D, Figure 1. Therefore, in typing an extended or tax and code including line b," the automatic causing of a return of th carriage from the line-end position determined for the ordinary call line a must be prevented and for this purpose the following mechanism may be provided.

The cam lever 3| is pivoted upon a headed stud 85 in an arm or wall extending leftwardly from a body block 88 supported by, but not binding the rock shaft'34. A U-shaped clip 89 suitably and rigidly fastened, as by riveting 85, Figure 2, to the wall 81 and embraces the cross rod 14 to keep said block 88 from turning about said shaft 34.

A transverse bar 9| is fulcrumed at one end on a fixed stud 92 spaced to the left of the body block 88 and extends rightwardly beyond the latter to a pivotal connection 93 with a link 94 that extends downwardly to a pivotal connection 95 with an ear 96 on a lever 91. Said lever 37 may be fulcrumed at at, like the type key levers l2,

- and extends forwardly through a guide slot I00 in endwise as by collars 15, Figure 4 Ordinarily,

the margin stop II, 12 along with the dog 62, is adjustable laterally to different stations and is located at any station by means of a pawl 15,

the comb plate 4|. A spring 99 tends to keep the lever 91 and hence the link 94 and bar 9| in normal positions wherein said lever 91 stops against the upper end of said slot I00. 'In the normal position of the bar 9|, a shoulder |0| thereof engages the left end of a cleat -|03 suitably fastened, as by rivets, not shown, to the underside of the block-88. The cleat I03 has an ear I04 to which is attached a spring I05 tensioned to urge the unit comprising 3|, 88, 89, I03 leftwardly, said unit therefore tending to shift leftwardly.

The fulcrum stud 92 for the shouldered bar 9| may be in a block I06 supported on but not binding the rock shaft 34. At its part I01, the block I06 may be supported by the cross rod 14 and may be fixed to the latter by set screws I08. The block I06 also presents an anchor I09for the spring I05.

With the lever 91 and bar 9| in normal positions, Figures 3 and 6, the spring I05 keeps the block 88 in normal position. with its cleat I03 against the shoulder I! of the bar. 9L and the latter prevents leftward shift of the block 88. Thus, the cam lever 31 is located laterally in a normal position, Figures 3 and 6, wherein it will be engageable and depressible by the carriage tappet 30 to depress the transverse bar 32 and so cause automatically a power return of the carriage to line start position when the carriage takes the letter fed step following the typing of the last digit in the Amt. column of the bill I5.

If the amount is, 'say, fifty cents or more and therefore subject to a tax, the typing of a line is to be extended into the Tax and Code" c01- umns. In order that the line may be thus extended, automatic causing of the return of the carriage from the Amt." column is to be prevented. This is accomplished by causing the lever 91 to be depressed as will be explained presently. The bar 9| is, of course, depressed about its fulcrum 92 by depression of the lever 91, and

its shoulder I 0| is thereby depressed below the cleat I03 of the block 88. It results immediately that the block 88, and its cam lever 3 I, are shifted leftwardly, along the rods 34, 31, by the force of the spring I and it will be obvious that the leftward shift may be stopp d by a secondary shoulder I I0 of the depressed bar 9|.

In its leftwardly shifted position, the cam lever 3I- is stationed forcoacting with the carriage tappet 30 to cause automatically 9, return of the carriage at the time when the carriage takes the letter-feeding step following the typing of the last character'in the Code column of the bill, said last character representing the end of the extended line. The downstroke of the key lever 91, and henceof the bar 9|, may be suitably limited by a stop I I I on the comb plate 4I.

Depression of the lever 91 about its fulcrum 90 and concomitant leftward shift of the cam lever 3| may be effected automatically through such operation of the typing mechanism as occurs in typing a toll charge of, say, 50 or more in the Amt." column of the bill I5. The mechanism for accomplishing this will now be described.

Brackets II2 of the carriage I1 support a rack H3 in which a plate-like stop H4 is placed. A vertical reed or counter-stop II 5 is guided for vertical movement in a fixture II 1 attached to the framework. A bracket plate II8 of the framework supports a fulcrum rod II9 for a tabulating key lever I20. A spring I2I keeps the parts in normal positions in which the top of a slot I22 of the reed bears on a cross rod I23 of the fixture H1, and the top end of the reed is out of the path of the stop II4 on the carriage. vThus, depression of the tabulating key lever I causes 'the reed 5 to be lifted into the path of the carriage stop H4 and, concomitantly; the reed rocks a shaft I24 which, by meansof a connection not shown, disengages the carriage feed rack 26 from the .usual pinion of the escapement mechanism to release the carriage I1 for resulting tabulat ing movement by the carriage spring motor 24.

one of the letter-spaced rack stations III, relatively to the read -I I5 that upon operation of the tabulating key lever I20, the carriage will be tabulated to the position for the tens-of-cents place or denomination in the Amt." column of the bill. In Figure 1 the arrow represents the printing point and the tens-cf-cents place in the Amt. column. at the printing point. Said tabulating key lever I20 may be operated after typing the last character in the Place-called column. If the Amt. to be typed is above the tens-of-cents denomination, the usual back spacer I26, Figure 4, may be operated to bring the carriage back for typing in, say, the units-of-dollars or tens-of-dollars denomination in the column.

When the carriage is positioned so that the tens-of-cents place of the Amt. column is at the printing point, the top edge of the carriage stop II4, working as a tappet, will have engaged a cam edge I21 of a jack or lever I28 so that the latter will have been rocked, clockwise, to the Figure 7 position about a fulcrum stud I29 on an arm I30 of a plate I3I of the fixture I I1.

Similarly, when the carriage is positioned so that the units-of-dollars place or the tens-ofdollars place of the Amt. column is at the prin ing point, the tappet II4 will have also engaged a cam edge I32 of a jack or lever I33 so that the latter will have been rocked clockwise about the stud I29 to the Figure 8 position.

Each of the levers I28, I33 is bent forwardly as at I34 for connection, by a link I35, to a corresponding similarly bent intermediate lever I36 pivoted on a stud I31 passing through the fixture plate I3I into the fixture In. Each intermediate lever I36 is articulated as at I38 to a corresponding one of upright thrust rods I39, I40. Said thrust rods each have a slot I4I for the cross rod I23 and the lower end of each thrust rod laterally fits a guide slot, as' at I42, in the fixture II1. Each thrust rod is operatively connected at its lower end, as at I43, to a corre-' der the numeral key levers I2 of the values 5, 6,

7, 8 and 9. Similarly, the bell crank I44 corresponding to the dollars denomination lever I33 is connected by a link I41 to a plate I48 extending crosswise only under the numeral type key levers I2 of the values 1, 2, 3 and 4. Each link,

I 45, or I41, is pivotally connected to a rearward 1y extending ear I49 of the corresponding plate I46 or I48, and each plate has a pair of forwardly extending ears I50 at which the plate is pivoted to corresponding arms I5I rigidly fastened to a transverse rock shaft I52 journaled in the framework. Another arm I53 rigidly fastened'to said rock shaft has a lateral pin I54 for engaging the lever 91 that is depressible for causinga leftward shift of thecam lever 3I' to prevent initiation at the "Amt." column of a return of the carriage.

Each train, from the lever I28 or the lever I33 to the corresponding plate I46 or I48, is held in normalposition by a spring I55 connected between the bell crank I44 and an anchor bar I56 meral key levers I2.

, or plates I46,

of the fixture H1, and said normal position may be determined by the bottom of the thrust rod slot I4I abutting the cross rod I23.

In the normal positions of said trains, their respective plates I46, I48 stand, as represented by the full line position of the plates in Figure 2, clear of-tongues I51 provided on the several nu- It will be apparent, novf, that if either or both levers I28, I33 stand rocked by means of the tappet II4 on the I48 will stand rocked, counterclockwise, to the dotted line position in Figure 2, under the numeral type key lever tongues I51.

Considering, now, that the carriage has been positioned for starting thetyping of a toll charge at the tens-of-cents place in the Amt.. column, it will be seen that only the lever I28 will stand rocked and the corresponding plate I46 will stand placed under the tongues I51 of the numeral key levers I2 having the values 5, 6, '7, 8 and 9, as in Figure '7. In such position of the carriage, the lever I33 will not stand rocked because its cam edge I32 is proportioned so that the carriage tappet II4 has passed therefrom, and therefore the corresponding plate I49 will stand clear of the tongues of the key levers having the values 1, 2, 3 and 4. Thus, with the carriage positioned for the tens-of-cents place in the Amt. column,

operation of any one of the numeral key levers II for 5, 6, 7 8 or 9 avails, through the effectively positioned plate I46, to rock the shaft I52 and thereby depress the lever 91 by means of the rock shaft arm I53 and its pin I54, and cause automatically 9. leftward shift'of the cam lever 3I for preventing automatic initiation of a return of the carriage from the Amt. column. Further, while said numeral key levers for the values 5, 6, '7, 8 and 9 are thus effective, the remaining key levers, for the values 1, 2, 3 and 4, are not effective in this wise at the tens-of-cents place, since the corresponding plate I49 is not effectively positioned.

Consider, now, that the carriage is in position for starting the typing'of a toll charge either at the units-of dollars place or teris-of-dollars carriage, the corresponding plate place in the Amt. column. In that case, not

only will the lever I28 stand rocked but the lever I33 will also stand rocked, by the tappet H4, and therefore both plates I46, I48 will stand rocked to efiective positions under the tongues I51, as in Figure 8, to the end that, with the carriage positioned for typing at the dollars place in the Amt. column, operation of any numeral key lever I2 from 1 to 9 in value, inclusive will result in automatic operation of the lever 91 for effecting a leftward shift of the cam lever 3I.

In completing the typing of a toll charge by typing the character in-the units-of-cents place of the Amt." column, any one of all the numeral key levers I2 from 0 to 9 may be used. Therefore, the cam edges I21, I32 are proportioned so that as the carriage moves from the tens-ofcents place to the units-of-cents place,-the tappet I I4 leaves said cam edges and the springs I55 may operate to restore the trains, from the levers I28, I33 to the plates I46, -I49, in order toremove said plates from under the tongues I51. Thus, in typing a toll charge less than 50, say, for example, a toll charge of 45, the operation of the key lever for typing the 5 in the units-ofvcents place in the Amt." column will not effect a leftward shift of the cam lever 3| as would be the case if that key lever were used to type 5 in the tens-of-cents place in the Amt. column.

It will be understood that the rightward extent of the cam edges I21, I32 may be commensurate with the desired number of places in the Amt. column preceding the tens-of-cents place. Thus, Figures 7 and 8 may be considered as representing-an' extent commensurate with typing toll charges up to 99.99 and including a punctuation space between dollars and cents, and the tappet II4 may be considered as being capable of rocking either lever I29 or I33 .only in the letter feed step which places the carriage inthe tens-of-dollars place of the Amt. column.

Referring now to the toll bill, Figure 1, the typing of the toll charges in the Amt." column is particularly illustrative for the operation of the mechanism described. Thus, with the carriage positioned at the tensof-cents place for typing in the Amt. column in each of the lines a, only the plate I46'of the two interponents or plates I46, I49 stands rocked to effective position as in Figure 7 and therefore only the key levers I2 for 5, 6, 'l, 8 and 9 will be 'operatively connected to the lever 91, and the key levers I2 for 1, 2, 3 and 4 will not be so connected. It follows that if the amount typed is less than 50, as exemplified by the amounts 40", 30, and 10, in the first three lines a" of the bill, the lever 91 will not be operated through the typing of these amounts and therefore the cam lever 3| will remain positioned, by means of the latch bar shoulder IIII, so as to be engaged by the caramount is 50 and since the numeral agent or key lever I2 for typing 5 in the tens-of-cents place is one of those operatively connected to the lever 91 by means of the carriage controlled train I29I46, the operation of that numeral key lever concomitantly operates-said lever 91 to depress the latch bar 9| and thus cause the cam lever 3|, with its supporting block 99, to be shifted leftwardly by the spring I95 preparatory to extending the typing of said fourth line of the bill into the Tax and "Code columns. The leftward shift of the block 88, with the cam lever 3|, is arrested by the secondary shoulder IIO of the latch bar 9I so as to place said cam lever 3I for engagement by the carriage tappet 30 as the carriage takes a letter-feed step following the typing of the entry in the Code column, the carriage being thus automatically caused to be returned from said Code column.

In the fifth and sixth lines b of the Figure 1 bill, the toll charges typed in the Amt. column are respectively 1.50 and 14.30. With the vcarriage positioned for the units-of-dollars or the tens-of-dollars place in the Amt. column, both plates or interponents I46, I49 will stand rocked under the numeral key lever tongues I51, as in Figure 8, so that all of the numeral agents or of any digit from 1 to 9 in the dollars places in the Amt. column will automatically cause said lever 91 to be operated for causing the cam lever 3| to be shifted leftwardly, preparatory to extending thetyping into the Tax and "Code" columns and having the carriage automatically returned upon typing the entry in the "Code column.

'ment by a pin I 6-6 in the wall 81.

The rightward or return movement of the carriage may serve automatically to restore or shift the unit 3I, 88, 89, I03 back to normal position. For this purpose, the clip 89 includes a lateral extension I59 to which is secured, by a screw and slot adjustment device I60, a plate I6I engageable by a pin I62 in the front bar I8 of the carriage. By means of the adjustment device I60, the plate I6I may be set so that said unit will have been restored or shifted rightwardly by the pin I62, in the carriage return movement, to place the left end of the cleat its about at of an inch to the right of the latch bar shoulder IOI when the carriage counterstop 13 stops against the stop lug 12. This permits the latch bar 9| to rise under the force of the key lever spring 99 and its shoulder IOI to confront the left end of the cleat I03 again. It will be obvious that when said unit is in its leftwardly shifted position, the bottom of the cleat I03 may 'abut a step I58 of the latch bar 9| to maintain the latter in depressed position.

It will .be understood that after banking or stopping in its return movement against the stop lug 12 the carriage may have the usual drop back movement of about a letter space clue to the usual back lash of the escapement 25. At the end of such drop back movementflthe carriage will be settled at the letter space or line start position corresponding to the first character space in the Place-called column. By such drop back movement of the carriage, its pin I62 recedes from the plate I6I to permit the unit 3I--I03 to be released from the bar shoulder IOI by depression of the lever 91. l

The wall 81 of the unit 3II03 may have a lug I63 to coact with the tappet 30 for positively limiting leftward movement of the carriage at either position of said unit. The dog 62 may have an anti-friction roller I64 for engagement with said tappet 30. The cam lever 3I may have a nose I65 for engaging the bar 32 and said cam lever may be stopped against upward displace- The bar 32 may be similar to the usual toothed bar employed in Underwood machines.

The lever 91 may be provided with a key I61 so that it may be manually operable independently at will if desired, said lever 91 being independently operable by reason of the one-way pin connection at I54 with the mechanism through which the numeral agents or key levers I2 operate said lever 91 The machine may be provided with a palm key tabulating lever I69 pivoted at I10 to the machine frame and connected by an intermediate lever I1I, pivoted at I12 to the machine frame, to
